jamal is making pancakes. He has 6 3/4 cups of batter, but he needs a total of 12 cups. How much more batter does Jamal need?

vampirchik [111]

Jamil has already 6 3/4 cups of butter.
He need 12. SO in order to get the needed butter, we subtract 6 3/4 to 12.

= 12 - 6 3/4
= 11 4/4 - 6 3/4
= 5 1/4

So Jamil needs 5 1/4 cups of butter to achieve the 12 cups.

You need to rent a video camera for your school project. Murphy's Camera charges a $30 rental fee plus $35 per day. Allied Renta

andreev551 [17]

A. If a camera is rented for 1 or 2 days, it would be logical to rent it from Murphy's.

B. If a camera is needed for more than 3 days, it would make sense to rent it from Allied rental.

C. Yes, if a camera is rented for 3 days both rentals charge the same money.

C. If you were need a camera for 3 days, you would have to pay $135 for both stores.

Step-by-step explanation:

Step 1; Murphy's camera costs $30 to rent and an additional $35 for each day of rental. So the equations are

y = $30 + (x × $35), where y is total cost and x is the number of days rented.

So for x = 1, y = $30 + (1 × $35) = $30 + $35 = $65

So for x = 2, y = $30 + (2 × $35) = $30 + $70 = $100

So for x = 3, y = $30 + (3 × $35) = $30 + $105 = $135

So for x = 4, y = $30 + (4 × $35) = $30 + $140 = $170

So for x = 5, y = $30 + (5 × $35) = $30 + $175 = $ 205.

Step 2; Allied rental costs $45 to rent and a $30 for each day of rental. So the equations are as follows

y = $45 + (x × $30), where y is total cost and x is the days rented

So for x = 1, $45 + (1 × $30) = $45 + $30 = $75

So for x = 2, $45 + (2 × $30) = $45 + $60 = $105

So for x = 3, $45 + (3 × $30) = $45 + $90 = $135

So for x = 4, $45 + (4 × $30) = $45 + $120 = $165

So for x = 5, $45 + (5 × $30) = $45 + $150 = $195

Step 3; Comparing both prices over 5 days. Murphy's is cheaper for until 2 days. On day 3 both the rentals cost the same but after day 4, allied rentals is the better option.

If the correlation coefficient is .87, is its relationship considered to be strong positive,weak positive,strong negative,weak n

myrzilka [38]

Answer:

strong positive correlation co efficient

Step-by-step explanation:

correlation:-

A correlation co-efficient is a numerical measure of some type of correlation,meaning a statistical relationship between two variables.

positive correlation:-

Positive correlation occurs when an increase in one variable increases the value in another.

Negative correlation:-

negative correlation occurs when an increase in one variable decreases the value of another.

Strong positive correlation:-

A co-efficient of correlation of + 0.87 indicates a strong positive correlation between the independent variables

Strong negative correlation:-

A co-efficient of correlation of - 0.87 indicates a strong negative correlation between the independent variables.

Zero correlation:-

There is no relationship is called zero correlation

weak positive correlation:-

A co-efficient of correlation below 0.2 indicates a weak positive correlation between the independent variables.

weak negative correlation:-

A co-efficient of correlation below -0.2 indicates a weak negative correlation between the independent variables.
